Abstract

Spacers are disposed at only positions corresponding to positions of pixels of one of the color layers, thereby widening the spacing at which the substrates are supported, the planar spacing between the spacers being widened to 5 pixels in the horizontal direction and 2 pixels in the vertical direction, thereby causing the substrates to flex so as to track a dimensional change in the gap that accompanies a temperature change in the liquid crystal between the substrates.

Claims

exact text as granted — not AI-modified
What is claimed is:  
     
       1. A liquid-crystal display device in which a liquid crystal is sealed within a gap established by first spacers between a pair of opposing substrates, wherein the spacing between positions at which said first spacers supporting said substrates is widened to at least 5 pixels horizontally and to at least 2 pixels vertically, so that said substrates flex so as to track a dimensional change of at least 0.2 μm in said gap caused by a temperature change in said liquid crystal. 
     
     
       2. A liquid-crystal display device according to claim  1 , wherein said display device includes pixels of three colors, said spacers are disposed at positions corresponding to pixels of one color, thereby widening said spacing between positions at which said first spacers support said substrates to at least 400 μm. 
     
     
       3. A liquid crystal display device according to claim  1 , wherein second spacers having a height that is shorter than said first spacers are provided between said first spacers, said substrates having flexed to track a dimensional change in said gap accompanying a temperature change in said liquid crystal are supported by said second spacers at a height shorter than that of said first spacers, thereby establishing a uniform gap between said substrates.
